Okay, we bought a new power shower to replace our old one and there is a seperate 4mm earth running along side the 6mmT+E. Thing is the single earth isn't long enough to reach the terminals. We were going to join another bit of cable on the end using a terminal block so it will reach.
My question is, does it matter the size of the earth, as in can it be any size as long as it is thicker than 4mm? I can join some 6mm cable on the end, but we have no 4mm.
